Zoe Saldana, one of Yelchin’s “Star Trek” co-stars, spoke about his life and legacy at the emotional memorial, saying, “It is a bittersweet moment, because we’re here for Anton, and he’s not here with us.”

“But it alleviates my heart knowing that we’ll keep him alive. We’re going to keep remembering him in the hopes that by practicing all the things he believed in and remembering all the love that he gave us, and all the joy he gave us, we’re able to just keep him here with us,” she said. She also read a chapter about friendship from “The Prophet” by Kahlil Gibran, according to PEOPLE.

Yelchin’s mother, Irina, also spoke about her son and remembered him as a “beautiful human being.” She dedicated a project to his memory, the Anton Yelchin Foundation, which will help young artists “who face career challenges due to debilitating disease or disability.”

“We want to keep Anton’s spirit, his legacy, alive for many, many years to come,” she said. “After Anton left, there are only a couple of things left to do. A foundation, photography book and sculpture. We accomplish two by today. The Anton Yelchin Foundation and the statue at Hollywood Forever, so he would be surrounded by the people he admired and to be in the middle of the city that he loved so much.”

His statue is located in the Garden of Legends at the cemetery, just steps away from musician Chris Cornell’s memorial.
